It started with a scribble
A late-night sketch from 2019. It took six years and a pile of rejected samples to become the mug in your hand.
The actual file. Untouched since 2019.

My mug slipped. The bar never did
I was powerlifting and tried to hook grip my coffee mug. My fingers couldn’t even fit. Smooth handles are made for looks, not control.
Then the obvious answer was right there. Every barbell is knurled for a reason. You grab it and you know it’s go time. That locked-in feel belonged on a mug.
The first version came off a 3D printer.
Twenty versions. Two silences
The first print
Three months after the sketch, the first test of whether a barbell grip even belonged on a mug.
December 2019 to December 2020. Life happened. The files sat.
Back on the printer
One print to prove the idea was still worth chasing.
March 2021 to March 2023. The long one.
Twenty versions in six weeks
When it came back, it came back fast. New versions came off the printer almost daily, each one fixing what the last got wrong.
Tested where it would live
It had to work at 6am, not just in CAD.
Then the market changed the plan.
The trend got there first
By mid-2023, tumblers had taken over the market. So the plan changed: the mug went on the shelf, and the first production push became a 40oz tumbler.
Steel wasn’t any kinder to the tumbler. The first metal samples arrived in June 2023, and the rejections started the same month.
Round after round got measured against the drawing, and most of them lost.
The handle got argued over long before the mug got built
No inspection lab. Eyes, a marker, and a standard
The 40oz Tuff Tumbler shipped first. Every early order was a drive to the post office. It paid the bills.
It was never the point.
The mug never stopped being the point.
You can’t calculate feel
The tumbler bought the time to build the mug right. Handle diameter matched to a real barbell. Knuckle spacing. Height. Knurl depth. Chamfer. Capacity. Every candidate got printed and picked up, morning after morning, and nothing survived unless it earned it.

The standards didn’t soften the second time around. Mug handle samples kept coming back wrong, and kept getting rejected.
The handle got so specific, it got patented.
One patented handle
Years of iteration settled on a 28mm knurled bar, the same diameter your hands already know. It’s patented now.
